Abstract
COUPEUSE ROTATIVE POUR COUPER EN TRONCONS SUCCESSIFS UNE MATIERE EN MOUVEMENT. UNE SORTIE DE FONCTION CORRESPONDANT A LA DETECTION D'IMPULSIONS D'AVANCEMENT DE LA MATIERE EST ENGENDREE CONFORMEMENT A UN COEFFICIENT D'ACCELERATIONDECELERATION DE MANIERE A DONNER UNE COURBE PREDETERMINEE DE VITESSE DE ROTATION DE LA COUPEUSE, QUI DEPEND DE LA RELATION ENTRE UNE LONGUEUR DE COUPE DE MATIERE L ET UNE LONGUEUR CIRCONFERENTIELLE INHERENTE L DU COUTEAU. LE CALCUL DE TROIS FONCTIONS DE COMMANDE, A SAVOIR UNE VITESSE DESIREE DE LA COUPEUSE, UNE ERREUR DE POURSUITE ET UNE ACCELERATION S'EFFECTUE SELON LA SORTIE DE FONCTION. LA COUPEUSE ROTATIVE SELON L'INVENTION EST CAPABLE DE REALISER LA COUPE AUTOMATIQUE CONTINUE DESIREE D'UNE MATIERE EN LONGUEURS DESIREES, AVEC UNE GRANDE PRECISION, ET AUSSI DE SURMONTER LES DEFAUTS DES COUPEUSES ROTATIVES ANTERIEURES.
